Hydra is a Sorceress Skill in Diablo II.


This skill enables the Sorceress to summon a beast of pure flame from the core of the world. The Hydra have been allies of the Zann Esu women for generations, owing their freedom in ancient times to the actions of the renowned Sorceress, Habacalva. They never fail to answer a call from a proven Sorceress, and stand ready to spit bolts of scorching magma at her enemies.

Fire Ball: +3% Fire damage per level

Hydra is very similar to the Assassin's Traps. It calls forth a three-headed monster made of fire that shoots Fire Bolts at its enemies. It cannot be attacked, and multiple Hydras can be summoned at once; having three or four Hydras on your side can be deceivingly powerful.


Hydra as seen in game

Although its synergies are minimal, it can benefit greatly from Fire Mastery. The listed damage is for each individual fire bolt fired by the Hydras. Each Hydra shoots 8 volleys (it takes 1 second to both "start up" and "cool down"), with 3 shots per volley.

The optimal spread between Mastery and synergies is: a total (including soft points as well as hard points) Mastery 15–16 points higher than hard points in synergies, until Mastery is capped. This number changes with gear or auras reducing enemy fire resistance, however.

Hydras attack autonomously once cast. Therefore, a sorceress can place them in strategic positions, such as from much farther away than other more direct skills, or around corners, and have them do the casting while the sorceress is in a relatively safe position.

This can be advantageous in the fight with Diablo, as one can utilize the safespots behind the jutting corners of the walls to remain entirely protected, while the hydras deal damage.
